Overview
The LABTOP BC217 bath thermostatic circulator is a thermostatic circulator with heating head. With the help of external circulating water or chilled down liquid tank, the temperature can reach room temperature or -20 ℃. The bath body is made of all stainless steel, and the outside is filled with aluminum silicate cotton insulation, which provides an economical solution for the sample to be placed directly in the water bath for thermostatic test. Optional external circulation adapter and external temperature sensor PT100 can be used for external temperature control and recycling application. Suitable for temperature control, material testing, quality control, analysis of samples, etc. Use environmentally friendly natural refrigerant with liquid level protection and over-temperature protection functions.
Features
1. Hardware over-temperature protection, the user can set the protection temperature through the knob, in the case of equipment program failure, it can still be over-temperature protection to avoid dry burning, in line with DIN12876 standard level III, flammability bath liquid can be used.
2. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load.
3. Optional multi-stage programmable controller, users can achieve multi-stage program control, such as regular heating, cooling, thermostatic, slope and the time of each section, each program can set the running time, the maximum time of each section is 999 hours.
4. Equipped with external temperature sensor interface, optional movable external temperature sensor, with professional PID TAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, can accurately control the bath external material temperature.
5. Pt100 temperature sensor, single point, two point and multi point temperature calibrating.
6. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics.
7. Optional related accessories are available for different internal and external applications.
8. The buzzer can be set to silent or audible.
9. A variety of operation modes are optional, and accidental power failure can be automatically restored (mode 1: power-on equipment stops after power failure, and the set value can be changed; mode 2: power-on equipment automatically runs after power failure, and the set value can be changed; mode 3: power-on equipment automatically runs after power failure, and the set value cannot be changed).
10. The device serial number can be checked by software.
11. Optional intelligent control functions: a variety of interfaces (RS485, RS232) to achieve remote communication and control the start and stop of equipment.
12. Optional normally open and normally closed 2 external contact points, can be connected to external alarms.
13. Optional set of 12V switch Output signal for controlling external solenoid valve.
14. An optional set of 5V external input switch signals can be used for external smart devices to control the start and stop of the instrument.
15. Optional 0-10V or 4-20mA analog signal input can be used for external smart devices to control the start and stop of the instrument.
Principle
The device is a thermostatic circulation unit that is heated by a built-in heating head and cooled down with the help of a chill down coil and an external circulating water or chill down tank, enabling a wide range of temperature control from room temperature to -20 ° C. It uses an intelligent PID Temperature Control mode combined with a Pt100 temperature sensor for accurate temperature measurement. Driven by a pressure/suction pump, the pump's pressure and Flow rate automatically adapt to the external load, ensuring uniform and stable temperature.
